f1 claim. (oral- 125) This invention relates to a Wrench, and more particularly to a wrench adapted to retain a nut thereon for placement where desired.

The principal object of the present invention is to provide a wrench for retaining a nut thereon for placement on a threaded shank of a bolt in places inaccessible to the hand of the user.

Other objects of the present invention are to provide a device having a threaded shank or end adapted to receive an internally threaded nut, the threaded shank being of a length equal to about one-half of th-e threads of th-e nut; to provide a shoulder on the shank adjacent the threads to provide a stop for the nut; to provide a sleeve on the shank having a socket adapted to engage the nut to turn the nut so that it will engage the bolt to which it is to be applied or to prevent turning of the nut for removal of the threaded shank from the nut; to provide a handle on the upper end of the shank; and to provide a device of this character simple, economical to manufacture and efficient in operation.

In accomplishing these and other objects of the present invention, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective vieW' of my device.

Fig. 2 is a Vertical elevational view partly in cross section to better illustrate the invention and showing the nut after it is attached to the bolt and the sleeve in elevated position on the shank.

Fig. 3 is a vertical elevational view partly in section showing the nut secured to the bolt an socket of the sleeve engaging nut.

Fig. 4 is a transverse cross section through the device taken on a lin-e 4 4, Fig. 2.

Referring more in detail to the drawings:

I designates a wrench embodying the features of my invention consisting of a shaft or rod 2 having a handle 3 on one end and provided with threads 4 on its opposite end. Adjacent the threads 4 is a ring or collar 5 rigidly secured to the shaft by welding or other suitable means. The ring 5 provides a shoulder 6 for a purpose later described.

While my device may be used for many purposes, it is particularly adaptable for placing of nuts in steel cars wherein recesses or sockets 'I are provided in the Wooden ends 8 of the car. A bolt 9 extends through the ends 8 and ter- Inmates short of the opening of the recess I as best illustrated in Figs. 2 and 3. The end of the bolt 9 is provided with threads I0. I I designates 2' t a nut having internal threads I2 and it will be obvious that it would be diiiicult to startl the nut on the threads I3 of the bolt S by hand due to the small recess 'I.

To place the nut IIron the threads III of the bolt 9 the nut isthreaded onto the threaded end 4 of the shaft 2 until the side face I3 thereof engages against thev shoulder E of the ring or collar 5 so as to retain the nut on the shank of the tool. The shaft with the nut on the end may then be inserted in the recess and by turning of the shank the nut II will engage the threads I Il of the bolt 9. By having the nut threaded on the shank it may be easily aligned with the threads on the bolt 9 so as to prevent cross threading,

When the nut is started on the threads IU of the bolt 9, the shaft 2 of the tool may be disengaged from the nut I I by reverse turning of the shaft and to prevent loosening of the nut I I from the bolt 9 due to the nut having become tight on the threads 4 of the shaft 2, I provide for holding of 'the nut to prevent turning. For this purpose a tubular member or sleeve I4 is sleeved over the shaft 2 as illustrated in Fig. 2. The upper end of the sleeve is provided with a handle member I5 for raising and lowering the sleeve on the shaft. The opposite end of the sleeve is provided with an outwardly flared circular member I-S provided with a plurality of slots I'I forming a socket adapted Ito engage over the nut Il as best illustrated in Fig. 3. While I have here illustrated a substantially square-shaped nut, it will be obvious that other shape nuts may be utilized. The corners I8 thereof are adapted to engage in the slots Il of the socket I6 on the end of the sleeve so that the sleeve may be held from rotating by the user to hold the nut in place and the threaded end 4 of the shaft 2 removed from lthe nut by reverse turning of the shaft. A washer 2Q is provided for the bolt '9 to fit in the recess 1.

An alternative manner of operation of the device is the nut I I may be placed on the threaded end 4 of the shaft 2, and the shaft and nut inserted in fthe recess 'I so that the nut will engage the end I9 of the bolt 9 as best illustrated in Fig. 2. The sleeve I4 may then be lowered on the shaft 2 so that the socket will engage over the nut II and the corners I8 engage in the slots II of the socket. Turning of the sleeve by the hand of the operator to the right will cause the nut I I t0 engage the threads IG of the bolt 9 and by holding of the shaft 2 of the tool stationary, the nut II will` be disengaged from the threaded end 3 4 of the shaft 2 so that it may be removed. While I have here shown a socket I6 on the end of the sleeve provided with slots for engaging the corners of the nut, it will be obvious that other forms of sockets may be utilized, such as sockets conforming to the shape of the nuts.

It will be obvious from the foregoing that my device may be utilized for either placement of nuts on a threaded bolt or removal of the nut from the bolt infplaces inaccessible to the hand of the operator. While the nut may be tightened to a certain extent on the threaded bolt 9, exftreme tightening of the nut may be accomplished by the usual tightening wol (not shown) if desired.

What I claim and desire to secure by Letters Patent is:

A device for placement of an internally threaded nut having cornersthereon on the threaded 4 a socket of substantially bell shape and formed integrally with the lower end of said sleeve and having longitudinal grooves therein for engaging the corners of said nut on said shaft whereby rotation of the sleeve will hold the nut on the threaded end of said bolt and permit disengagement of the shaft from the nut.
